Transistor tachometer schematic

3225 50M crystal
100V, 250mA, surface mount, high speed switching diode
Crystal oscillator
The transistor tachometer schematic uses only a single transistor, which is probably the simplest tachometer schematic. The input to this circuit can be used to take the pickup ignition coil, or other lines to achieve the ignition waveform. Transistor tachometer schematic
